Material Examined. Holotype: CHINA: Yunnan: Gongshan Co. Dulongjiang Township, Haban Falls 0.5 airkm from Qinlangdang village along Dulong Jiang , 27.67934°N, 98.27291°E, 1265 m, 1 September 2006, forest, rocky outcrops, night, J.A. Miller, D.H. Kavanaugh, JM06090106 (CASENT 9024371, HNU), 1 ♀.

Etymology. Derived from the name of the type locality. The epithet is a noun in apposition.

Diagnosis. Distinguished from most other Chinese Mysmena species by the lack of a well defined scape (Fig. 21I); distinguished from M. goudao by having the spermathecae simple and round (Fig. 21I) rather than part of a complex with the copulatory ducts (Fig. 21G); distinguished from M. shibali by the separation of the spermathecae (about 1.5 times their diameter in M. haban , nearly three times their diameter in M. shibali ; Fig. 31B), the path of the fertilization ducts (J-shaped in M. haban , sinuous in M. shibali ), and the presence of a posterior abdominal tubercle in M. shibali (absent in M. haban ).

Description. Carapace brown, darker margin and through head region. Sternum dusky yellow. Legs pale yellow, darker distally. Indistinct femoral spots on legs I and II. Abdomen pale tan with pair of broken white lines laterally and posteriorly (higher posteriorly than laterally), darker ventral to white stripe and with dark anterior patch; posterior tubercle absent.

Vulva: External structures subtle. Round spermathecae separated by about 1.5 times their diameter. Copulatory ducts weakly sclerotized throughout terminating in pair of wide atria; region between atria with wrinkled texture. Fertilization ducts relatively well sclerotized, arise from posterior part of spermathecae, run mesally, spiral at tip (Fig. 21I).

Female (holotype): Total length 0.75, carapace 0.31 long, 0.31 wide, clypeus 0.05, sternum 0.22 long, 0.22 wide, coxa IV separated by 2.20 times their width. Macrosetae: Leg I: patella d1, tibia d1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.30; TmII: 0.33; TmIII: 0.31. Leg measurements: see Appendix A.

Male unknown.
